NSInternalInconsistencyException: Built-in appearance SystemAppearance not found

[ghost]

When using node-mac-notifier, getting the following exception which crashes the renderer. Facing this in macOS Catalina. Works fine in macOS Mojave. node-mac-notifier version : 1.2.0

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Critical error: required built-in appearance SystemAppearance not found'

This issue looks similar, but the trace looks different.

Sending notification without an icon seems to work, fails with the above exception when providing data url or image url

remote.require('node-mac-notifier') fixed this issue for me

Based on a report by a zulip-desktop user, this crash seems to follow the warning in #31. I wonder if that’s the root cause?

objc[87760]: Class NotificationCenterDelegate is implemented in both […]/node_modules/electron/dist/Electron.app/Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework (0x10974d0c0) and […]/node_modules/node-mac-notifier/build/Release/Notification.node (0x10a806a20). One of the two will be used. Which one is undefined.

Chromium and node-mac-notifier both define an @interface NotificationCenterDelegate. Can we rename the one in node-mac-notifier?
